That's an excellent point. There may have been wood particles still in the cabinet and entered the driver.
If the driver is disconnected, and shaken with the breather hole facing down, maybe the possible debris will fall out?

Also, try holding the driver while it's thumping, out of the box, turn it on it's side and then try turning it on the other sides.

Ok, that sounded stupid. basically, what I'm getting at is the vc might not be aligned right, and turning it on its side might clear up the noise.

If it does, I'd guess the driver needs to be replaced. Luckily eD is really good about their warranty policy...although it sucks to have problems with a brand new sub, I'll admit.

Yeah, nothings perfect. It may be defective.

That finish looks ugly - more pro audio than home audio IMO. I agree with others here that a normal painted finish or optional veneer would be better.

Is it me or does the inside have a ton of overspray???

I have sound equipment.

It's an aquired taste. Not as bad as you think. Different. I got used to it.

As long the over spray doesn't effect performance, I don't care.

I am still surprised that they don't have any filler/dampening material. Usually a must to keep subs from sounding boomy and distorted. My SVS PB10 is probably 1/3 full of what looks like house insulation. Any other thoughts on this?

It's debateable. Some use them and some don't. The A2-300 doesn't sound boomy at all. But since you brought it up, I may experiment. I'll line the walls with some house insulation and hear the results. It's not going to happen anytime soon, so be patient.

Be careful when you do that, you may end up with a fiberglass insulation canon

Yes, your right. Might go with polyfill instead.

You will want to line the interior walls with about 2" thick fiberglass batting rather than using any type of fill material for a ported sub.

All you're trying to do in this case is knock down any higher frequency mechanical rattles or box resonances, not affect the perfomance of the driver/port combination.

Lol, I added fiberglass insulation to a yamaha subwoofer and that's what I got! Luckily, the speaker grill/cover also covered the port opening and kept the flying glass at bay. I'm letting my dad use that sub in his HT.

Really p***ed off.

Took delivery of the A2-250 on Wednesday and it was working ok until this evening. I switched it on this evening and nothing unless I turn the volume up to maximum and then just a sort of muffled crackle. All the connections are ok and the green light is on, the only other thing I can think of is a problem with my AV receiver. Anyone got any ideas please?

John,

Try plugging the some cables straight from the source (IE dvd player or ipod) into your sub. This will gaurantee that there is a signal reaching the sub. IF it still does not work then you probably have a problem. A muffled crackle could be a blown Voice Coil (At least in my limited expierence).

Contact ED immediately. You are under warranty, they may be able to drop ship you a new sub quickly if the sub is the problem. Give them a chance to respond.

Thanks, I've tried putting putting the coax connection from the DVD directly to the sub, no signal getting through to the sub. I don't see how that would work without any amplification?

I think you're putting the DIGITAL output of the DVD player into the sub. That means you were sending it 1's and 0's. You gotta use one of the analog audio outputs on the DVD player (Red or White RCA Jack) to get any kind of a signal through. And as for amplification, all the amplification is done by the amp inside of the subwoofer.

I don't think the coax connection would work since it sends a digital signal. Connect the red and white rca's on the back of the dvd and plug them into the l and r connections on the amp. There should ve plenty of signal from the dvd player

Yes, tried it this morning with a direct connection from my DVD and it's making a loud thumping noise with a muffled crackle. I've rang eD and was lucky enough to catch somebody in. He thinks that it's probably the amp at fault or possibly the speaker, there nothing that can be done 'till Monday anyway, but whichever part is faulty they are going to ship one out to me. Meanwhile I'm going to have a look inside and check for loose connections.

Parts and fit myself.

Actually he would've sent me an amp out but as they can't send one out until Monday anyway and he hasn't really decided whether it's the amp or speaker that's at fault, I said we'll leave it over the weekend and phone first thing Monday.

I've checked it direct from DVD with an analog signal and the speaker is pumping well, the only way I can describe it is as a thumping crackly tick.
Set up in the normal manner it won't seem to accept a digital signal unless the volume is at maximum and then it's not very loud at all.
The last test which eD suggested, was to directly connect the speaker wires from my receiver to the inline of the sub, which produced nothing apart from one pump of the speaker when I switched it on and one pump when I switched it off.
Lastly I took the back off to look for loose connections and there were none.

That narrows it down.

Well I am taking the plunge as of today. I just put in my order for the a2-300. Now I have to go find a 50ft coaxial to run it to the back of my room.

Get ready to wait for a while. My order was put in 12/05/06 and it's still in 'box construction".

My order was placed on 11/28 and I was told last monday that he thought it was going to paint... Still shows "in woodshop" as of today. On another note, im picking up a Denon 3806 this week! Im currently running 5 of the eD MTM's, going to order a set of towers and another sub to finish off the system.
